An electrochemical approach for the preparation of monofluorides from α,β-unsaturated carboxylic acids and heteroaromatics with readily available 2-fluoromalonate esters as monofluoroalkyl radical precursors has been developed. The electrosynthesis employs ferrocene (Cp2Fe) as a catalyst in a simple undivided cell with a broad substrate scope, which obviates the need for sacrificial oxidizing reagents
已经开发了一种用于从 α,β-不饱和羧酸和杂芳烃制备单氟化物的电化学方法,使用容易获得的 2-氟丙二酸酯作为单氟烷基自由基前体。电合成采用二茂铁 (Cp 2 Fe) 作为催化剂,在一个简单的未分割电池中,底物范围广泛,无需牺牲氧化剂。
